Overnight pulse-oximetry (PO), as the only non-invasive method assessing arterial blood oxygenation during sleep, became widely used additional criterion for the long-term oxygen therapy especially in chronic obstructive pulmonary disease (COPD) patients. The aim of this study was to assess the reproductibility of pulse-oximetry in COPD patients. We studied 20 stable COPD pts mean age 64.6 +/- 7.2 years with severe airway obstruction-FEV1 = 0.87 +/- 0.33 L and hypoxaemia-PaO2 = 55.8 +/- 6.9 mmHg. Three PO were performed in each patient at one and seven nights intervals. There were no statistically significant differences in results obtained at all three PO. The mean oxygen saturation changed from one night to another only by 0.1%, the initial and final-maximally by 0.5%. High correlations for mean oxygen saturation (r = 0.94 and 0.78 respectively), initial oxygen saturation (r = 0.78 and 0.52) and final oxygen saturation (r = 0.69 and 0.77) were observed. In conclusion PO is reproducible in stable COPD patients at 1 and 7 days intervals.
夜间脉搏血氧饱和度测定（PO）作为睡眠期间评估动脉血氧合的唯一非侵入性方法，已成为长期氧疗广泛应用的附加标准，尤其是在慢性阻塞性肺疾病（COPD）患者中。本研究的目的是评估COPD患者脉搏血氧饱和度测定的可重复性。我们研究了20例稳定期COPD患者，平均年龄64.6±7.2岁，有严重气道阻塞（FEV1 = 0.87±0.33L）和低氧血症（PaO2 = 55.8±6.9mmHg）。每位患者在间隔1晚和7晚时进行3次PO测定。所有3次PO测定结果均无统计学显著差异。平均血氧饱和度从一晚到另一晚仅变化0.1%，最初和最终最大变化0.5%。观察到平均血氧饱和度（分别为r = 0.94和0.78）、初始血氧饱和度（r = 0.78和0.52）和最终血氧饱和度（r = 0.69和0.77）之间具有高度相关性。总之，在稳定期COPD患者中，间隔1天和7天进行的PO测定具有可重复性。
